For handling tires are it, the stickier and wider you can get. As for suspension the front does 80% of the work just like braking. A front sway bar is a must and the 1.03 bars would be good along with good shocks and brakes.
Then for the back is to select springs and maybe sway bar to balance out the front ideally you want a neutral car with no over or under steer but most build in a little understeer since it's safer than oversteer.
